The light-transmitting lamp cover 8 is detachably connected to the front wheel frame 2 or the rear wheel frame 1, allowing the lighting lamp 5 to be hidden and stored in the mounting groove 213. In this structure, the lighting lamp 5 does not protrude from the outside of the frame, making it less susceptible to damage during use and extending the service life of the wheelchair lamp. Furthermore, the lighting lamp 5 is mounted on the front wheel frame 2 and the rear wheel frame 1 at a low installation height, which facilitates the lighting lamp 5 to illuminate the ground and makes it convenient for the user.

[0033] The mounting groove 213 of this utility model is provided with a lamp holder 6 and a reflector 7. The lamp holder 6 is detachably mounted in the mounting groove 213 by fasteners. The reflector 7 is located between the lamp holder 6 and the light-transmitting lamp cover 8. The light-transmitting lamp cover 8 and the lamp holder 6 are ultrasonically welded together, and the reflector 7 is pressed against the lamp holder 6. The ultrasonic welding of the light-transmitting lamp cover 8 and the lamp holder 6 helps to reduce the entry of moisture and dust into the light-transmitting lamp cover 8, avoids damage to the lighting lamp 5, and helps to extend the service life of the lighting lamp 5. In addition, the structure in which the light-transmitting lamp cover 8 presses against the reflector 7 against the lamp holder 6 facilitates the assembly and production of wheelchairs.

[0034] To facilitate the illumination of the ground in front of the wheelchair by the lighting lamp 5, it is preferable that the front wheel frame 2 is provided with a mounting groove 213. The front wheel frame 2 includes a connecting rod 211 hinged to the rear wheel frame 1. The connecting rod 211 is inclined downwards and forwards of the wheelchair. A vertically extending mounting part 212 is provided on the connecting rod 211. The mounting groove 213 is located at the front end of the mounting part 212. The connecting rod 211, which is inclined downwards and forwards of the wheelchair, facilitates the stable deployment of the front wheel frame 2 and the rear wheel frame 1. The vertically extending mounting part 212 facilitates the installation of the lighting lamp 5 on the front side of the front wheel frame 2, so that the lighting lamp 5 can illuminate the front of the wheelchair, making it convenient for the user.

[0035] The frame is provided with a front wheel frame 2 and a rear wheel frame 1 on both sides. The connecting rods 211 on the front wheel frames 2 on both sides bend and extend to the sides of the frame, so that the mounting parts 212 on the front wheel frames 2 on both sides are far apart, and the lighting lamps 5 on the front wheel frames 2 on both sides are far apart. This structure can prevent the user's legs from blocking the lighting lamps 5 during use, making it convenient for the user to use the wheelchair.

[0036] In this embodiment, the connecting rods 211 on the two front wheel frames 2 bend and extend to both sides of the frame, so that the mounting parts 212 on the two front wheel frames 2 are located on both sides of the seat cushion 4, and the lighting lamps 5 on the two front wheel frames 2 are located on both sides of the seat cushion 4. This structure can further prevent the user's legs from blocking the lighting lamps 5, making it convenient for the user to use the wheelchair.

[0037] The connecting rod 211 is provided with an electrical wire groove 214 that communicates with the mounting groove 213. The wire 51 passes through the electrical wire groove 214 into the mounting groove 213 and is electrically connected to the lighting lamp 5. The electrical wire groove 214 in the connecting rod 211 helps to reduce and avoid the wire 51 connected to the lighting lamp 5 from being exposed, which is conducive to the stable installation of the wire 51 at the connection position with the lighting lamp 5 and avoids damage to the connection position of the wire 51 with the lighting lamp 5.

[0038] The front wheel frame 2 described in this utility model includes a detachably connected wheel frame body 21 and a cover plate 22. The cover plate 22 is detachably disposed on one side of the connecting rod 211, and the wire groove 214 is formed between the cover plate 22 and the connecting rod 211.

[0039] In this embodiment, the wheel frame body 21 is provided with a positioning hole 217 and a snap-fit ​​part 218. The cover plate 22 is provided with a positioning protrusion 221 and an elastic hook 222 that cooperate with the positioning hole 217 and the snap-fit ​​part 218, respectively. The elastic hook 222 is provided with a guide surface. After the positioning protrusion 221 cooperates with the positioning hole 217, the side wall of the snap-fit ​​part 218 can abut against the guide surface and drive the elastic hook 222 to deform, thereby cooperating with the snap-fit ​​part 218, and thus fixing the wheel frame body 21 and the cover plate 22 relatively. The positioning hole 217, the snap-fit ​​part 218, the positioning protrusion 221 and the elastic hook 222 facilitate the rapid assembly of the wheel frame body 21 and the cover plate 22. Moreover, this structure facilitates the stable connection of the wheel frame body 21 and the cover plate 22, and avoids the wheel frame body 21 and the cover plate 22 from accidentally separating during use.

[0040] Preferably, the front wheel frame 2 and the rear wheel frame 1 are rotatably connected by fasteners, and the fasteners pass through the wheel frame body 21 and the cover plate 22. This structure is conducive to the stable connection between the wheel frame body 21 and the cover plate 22 and avoids loosening of the connection during use.

[0041] The mounting groove 213 of this utility model is provided with a positioning groove 215, in which a nut 24 is installed. Below the positioning groove 215, there is a mounting hole 216, in which a mounting post 23 is provided.
